VALVE MECHANISM.

Specification of Letters Patent.

Patented Oct. 3, 1911.

To all whom it may concern:

Be it known that I, WVlLLIAM I. MORGAN, a citlzen of the United States,residing at Seaford, in the county of Nassau and State of New York, haveinvented certain new and useful Improvements in Valve Mechanism, ofwhichthe following is a full, clear, and exact specification.

This invention relates to valve mechanism for hydraulic apparatus, andhas particular reference to' apparatus for controlling the applicationof hydraulic pressure to a jack or other fluid pressure apparatus, suchapparatus comprising means whereby the pressure upon the jack or otherapparatus may be quickly and conveniently released.

One object of the invention is to provide peculiarly advantageous valvemechanism of the character described which shall contain all thenecessary valves and passages for the control and conveyance of thefluid from a reservoir to the pump and from the pump to the apparatusoperated by the hydraulic pressure, as a jack, the valve mechanism beingconnected with the pump by a single pipe which contains the to and frompassage to the pump, the valve mechanism being detachably connected tothe pump structure. The valve structure being thus separated from thatof the pump, it can, in case of any derangement of the valves, beseparated therefrom, a new valve structure substituted, and in thismanner valve structures may be repaired or re-adjusted withoutinterfering with the continuous operation of the pump for a longer timethan is necessary to detach one valve structure and attach another. Thisis an important consideration in apparatus of the character describedfor the reason that it is peculiarly liable to be deranged by reason ofsand or other foreign material becoming lodged therein. This is due tothe fact that the apparatus must be used out of doors and under varioustemporary and makeshift conditions and where the best available watersupply is often full of dirt.

The valve structure of the present invention is peculiarly adapted tofulfil the above conditions.

The valve structure referred to comprises inlet and outlet valves forthe pump and a release valve for'the jack or other hydraulicallyoperated apparatus. The inlet and outlet valves, or what may bedesignated as the pump valves, may be located adjacent to the pump. Onthe other hand, the pressure release valve for the jack should belocated near the jack so that the pressure can be controlled from thatvicinity. According to the present invention, therefore, the valvestructure containing the inlet and outlet valves and that containing thepressure release valve are so mounted that the two valve structures areseparable so that they may be placed at varying distances apart,according to the relative locations of the pump and jack. Where the jackand pump are close together the two valve structures may be screwedtogether, as shown in the drawing.

A further object of the invention is to provide valves which arepeculiarly fitted for the duty which they are to perform. It has alreadybeen noted that apparatus of the character to which the presentinvention relates is quite liable to have sand or other foreignsubstance find its way to the interior of the apparatus. This foreignmatter becoming lodged upon valve seats would prevent the proper closingof the valves and produce improper operation of the ap paratus. Also,the scratching and wearing away of the valves is liable to cause a poorfit between the respective valves and valve seats. According to thepresent invention, ball valves in vertical passages are provided. Theresult is that none of the valve seats are flat, and therefore sand orother foreign matter cannot find lodgment on them. Also, the valves areself-grinding so that any abrasions onthe seats which may occur will beautomatically corrected. p

The invention with respect to a preferred embodiment thereof is shown inthe accompanying. drawings, wherein- Figure 1 is a vertical section of apump and valve mechanism, and Fig. 2 is a crosssection of a valveoperating rod which may be used.

Referring to the drawings, 1 represents a casing or body having thereinthe to and from passage 2 to the pump P. The passage 2 communicates witha vertical stralght passage 3 formed in the caslng l. Thls pas sage hasan inlet valve 4 which opens to admit water or other fluid to the pumpthrough the inlet passage 5, which latter will be connected with asource of supply. Upon the other side of the to and from passage 2 thereis located in the passage 3 an outlet valve 6 which is opened by thepressure of the fluid from the pump to admit the same to the jack orother hydraulic apparatus which is connected through. the pressurepassage 7 which extends through the casing 1 containing the releasevalve. The valves 4 and 6 are ball valves for reasons hereinbefore setforth. The balls are of different diameters, as shown, and theycooperate with seats of different diameters, as also shown. The passage3 comprises sections of different diameters, as shown, to accommodatethe different sized balls, and in view of the fact that the passage isstraight it may be formed by boring, which materially facilitates themanufacture besides producing a compact and easily accessible structure.The end of the casing is closed by a screw plug 19, as shown. Betweenthe valve 4 and the valve 6 is a ribbed rod 16, shown in cross-sectionin Fig. 2, and between the valve 6 and the plug 19 is inserted a similarrod 18. These rods serve to limit the range of movement of the balls 4and 6, and it will be observed that the ribs provide passages throughwhich the fluid can flow, and that exterior grooves are provided in therods 16 and 18, which grooves are respectively opposite the passages 2and 7 so that the flow is not obstructed, no matter in what position therods may be.

The release valve structure comprising the casing l is detachablyconnected to the ump valve structure, as before described. This lastvalve structure has a passage 27 which is connected in any suitable waywith the supply reservoir, the connection between which and the pressurepassage 7 is controlled by a ball valve 24. This ball 24 cooperates witha seat which is formed upon the end of a nipple 22 which is screwed intothe casing 1, the position of the valve seat being thereby adjustable.The nipple can be locked in any adjusted position by means of a lock nut23. Mounted within the nipple is a releasing screw 25 having branchedpassage 26 which communicates with a passage 27, but is normally closedfrom the passage 7 by the seating of the valve 24. The screw 25 has anexternal groove to register with the passage 27 so as to permit thewater to flow freely at different positions of the screw. When the screw25 is screwed up to unseat the valve 24, the pressure is released fromthe jack or other apparatus and exhausts through passage 27. But oneplug is necessary to confine the balls 4 and 6, as the passage 3 is madesufliciently large to permit the ball 4 to be dropped from the top andthen the larger ball 6 is put in to be confined by the plug 19.

Having thus described my invention, I declare that what I claim as newand desire to secure by Letters Patent, is:-

1. The combination'with a pump, of a valve mechanism comprising a casingcon- 'taining inlet and outlet valves for said pump and constructed toretain said valves in operative positions, a second casing constructedwith a passage leading from said outlet valve toward the apparatus to beoperated, a ball valve for relieving pressure in the passage in saidsecond casing, and a screw having a passage for the fluid mounted insaid casing and adapted to contact with the ball of the valve to lift itfrom its seat.
